We've all heard 50/50 on the mechanical rollers living on the street. With my new motor, I've went with Isky's EZ-Roll lifters, that have a solid bearing, not needles. They did go through a few different type's of material to get where they are today, supposedly,... with no issues. I also bought a cam core from "Howards" , which sells a lot to other company's. Isky will do the grinding. I also got their "Tool Room" springs and valvetrain hardware. I'm hoping that this kind of newer,..... technology solves the street issue.
You might check with them as I have, as see what they recommend.
Excaliber- "Another problem with getting enough
oil to the lifter is how modern technology (engine building, windage trays and such) keeps the
oil away from the crank. So your "splash" or "
oil spray" from the crank to the camshaft lobe area is greatly reduced. Thereby starving the cam/lifters."
I guess I've never thought of the windage tray, crank scraper, causing this affect. Just how much has been studied about this poentional problem ?
Very good question !
